Definitions
- the invention relates to a device with the features listed in the preamble of claim 1.
- the tool head shank is penetrated by radial openings for receiving and for the direct action of the clamping balls on the tool shank.
- the tool head shank has the circumferential shape of a cone, in particular a standard cone.
- the invention has for its object to provide a device of the type mentioned in such a way that it enables a quick replacement of the tool heads, for example by robots, and still ensures high vibration resistance of the clamped tool head and high wear resistance. This object is achieved by the characterizing features of claim 1.
- the clamping device holds the clamped tool head both in the radial and in the axial direction, which also ensures a high repeatability of the clamping.
- the pressure distribution can be determined by the choice of the angle which the clamping surfaces of the clamping elements or the inner cone-shaped side wall of the inner ring groove of the tool head shaft which is acted upon by them forms with the axis of the drive spindle. This angle can be 45 °, for example.
- the clamping principle according to the invention generally makes use of the inherent elasticity of the material steel and the deformation of the tubular tool head shaft that occurs during the clamping process remains in its elastic region, the clamping contact between the tool head shaft and the spindle recess is automatically released when the clamping balls are returned to their rest position.
- the ring shoulder of the recess of the work spindle with the corresponding annular projection of the tool head shank assumes a fit between the recess of the work spindle and the tool head shank. Because these fitting parts are positioned near the end face of the work spindle in the tensioned state, they are at a great distance from the area of action of the tensioning elements. As a result, this fit area is not subject to any deformation effects arising from the clamping process. As a result, a particularly tight fit can be selected without impairing operational safety.
- the positioning of these fitting parts in the front area of the spindle recess adjoining the end face of the drive spindle also does not impede a tight fit of the changing process. The fit lies in the area closest to the cutting edge with a comparatively small lever arm. The lack of deformation effects on the ring projection of the tool head shank is favored by the teaching according to claim 6.
- the teaching of claim 7 is used for repeatable, axial positioning of the tool head.
- the teaching according to claim 9 favors a safe insertion of the tool head shank into the spindle recess. Even if the longitudinal axes of the tool head shank and work spindle do not exactly coincide, unimpeded threading of the tool head shank into the spindle recess is guaranteed. In this case, the flank formation also serves to reliably guide the tool head shank during the alternating movement.
- the clamping and changing device is effective between the drive spindle 1 of a machine tool (not shown in detail) and a tool head 2 to be clamped thereon.
- the tool head 2 in the exemplary embodiment according to FIG. 1 is a milling cutter.
- the handle groove 3 surrounding the tool head 2, which in the clamped state (Fig. 1.4) is close to the free end of the drive spindle 1, is used to attack a robot arm with which different tool heads 2 are successively fed to the drive spindle 1 and removed again when replaced.
- the diameter of the essentially cylindrical clamping head 10 is dimensioned such that the clamping head keeps an annular space 14 in the recess 6 free around it by a corresponding distance 12 from the inner peripheral wall 13 of the recess 6.
- the shaft 7 of the tool head 2 can be inserted in the axial direction 15 into the annular space 14 of the spindle recess 6 and can be clamped therein by the clamping unit.
- the clamping head 10 of the clamping unit supports a clamping rod 16 which can be displaced in the axial direction 15 of the drive spindle 1.
- the clamping direction of the clamping rod 16 is identified by 17.
- the release direction is opposite.
- the clamping rod is provided on its circumference with a longitudinal groove 18 into which the screw-in end 19 of a grub screw 20 screwed into the clamping head 10 engages in the radial direction.
- the clamping rod 16 is held non-rotatably within the clamping head 10.
- the clamping head 10 is inserted as a separate component in the work spindle 1 and held in its position by the fixing screw 21.
- the clamping head 10 is penetrated in its axial region protruding into the recess 6 by radial guide holes 22, in each of which a clamping ball 23 is inserted.
- a total of three clamping balls 23 and, accordingly, three guide bores 22 are distributed uniformly over the circumference of the clamping head 10.
- the adjacent axes 24 of the guide bores 22 therefore together form an angle 25 of 120 ° in each case (FIG. 5).
- the clamping balls 23 are spread apart radially outwards by an axial pulling movement of the clamping rod 16 in the clamping direction 17. They thus cause the clamping of the tool head 2 on the drive spindle 1, as described in more detail below.
- the tool head shank 7 is formed in its free end region 26 as a tubular body or as a drilling cylinder concentric with the axis of rotation 8, the interior 27 of which is enclosed by an inner cylinder surface 28.
- An inner ring groove 29 is also made concentrically with the axis of rotation 8 in the inner cylinder surface 28 and has a groove side wall 30 inclined in the manner of an inner cone on its machine tool-side tightening side.
- the groove side wall 30 forms an acute angle 31, which closes in the clamping direction 17, with the axis of rotation 8 or the spindle axis of rotation 5.
- annular groove 33 is made in the circumferential surface 32 of the clamping head 10, in which recessed and non-displaceable in the axial direction 15 and in the circumferential direction 15a (FIG. 6), but three clamping elements 34 can be spread apart in the radial direction.
- One clamping element 34 is acted upon on its inside 35 by a clamping ball 23.
- the tensioning elements 34 are designed like a ring segment (FIGS. 5, 6). Their ends pointing in the circumferential direction 15a are at a distance 36 from one another.
- the Clamping balls 23 act in a flat manner on the clamping elements 34 in insert recesses 37 attached to their inner sides 35.
- the clamping elements 34 act via their clamping surfaces 38 shaped as outer cone segments to generate the clamping pressure on the groove side wall 30 of the inner annular groove 29 of the tool head shank 7.
- the clamping elements 34 exert both an axial pressure acting axially in the clamping direction 17 and a radial pressure in the expanding direction 39 on the tool head shank 7, which thereby expands slightly elastically and braces largely in a flat manner with the inner circumferential wall 13 of the recess 6.
- the tool head 2 is pressed with its flange face 63 in the axial direction 15 against the end face 4 of the drive spindle 1.
- the outer circumference 40 of the tool head shank 7 is designed as a cylindrical fitting pin which can be inserted with a sliding fit into the recess 6 of the drive spindle 1 which is designed as a cylindrical bore.
- the clamping elements 34 are each provided on their side facing away from the clamping surfaces 38 with a conical segment-like chamfer surface 41 which, with the axis of rotation 8 or the spindle axis of rotation 5, form an acute angle 42 which closes in the direction of the tool head 2.
- the opening edge 43 of the interior 27 of the tool head shank 2 is provided with a chamfer 44.
- the edge-side front region of the recess 6 adjoining the end face 4 of the drive spindle 1 is designed as a cylindrical ring shoulder 45.
- the cylindrical ring shoulder 45 has an inner diameter which is larger than the inner diameter of the inner circumferential wall 13 of the recess 6 in its area which is approximated to the bottom 9.
- the inner circumferential wall of the cylindrical ring shoulder 45 forms a snug fit for a corresponding ring projection 47 of the tool head shaft 7.
- the ring projection 47 of the tool head shaft 7 is arranged outside the tubular end region 26 of the tool head shaft 7. In the inserted position (FIGS. 3, 4), the annular projection 47 of the tool head shank 7 ends to form a free space 48 with an axial spacing 49 in front of the end face 50 of the cylindrical ring shoulder 45.
- an inner cone-like transition ring surface 51 which acts as an insertion chamfer.
- annular bead 53 is formed, the outer diameter of which is smaller than the outer diameter of the outer circumference 40 of the tool head shank 7.
- the circumference of the annular bead 53 is separated from the outer circumference 40 of the tool head shank 7 by an annular groove 54.
- the flank 55 of the annular groove 54 which merges into the outer circumference 40 of the tool head shank 7 has the circumferential shape of a truncated cone.
- the tensioning elements 34 have an axial extension 57 which engages in a radially outwardly directed guide 56 on the lower side wall 33a of the annular groove 33, in order to ensure that the tensioning elements 34 can move only in the radial direction 39 and back.
- a limiting device limiting the radial displacement of the clamping elements 34 in the spreading direction 39 is provided on the clamping head 10.
- This consists of grub screws 59 screwed in from the end face 58 of the clamping head 10, the front ends 60 of which can be screwed through the upper side wall of the annular groove 33 of the clamping head 10 and protrude into the radial displacement away from the clamping elements 34.
- the end face 4 of the drive spindle 1 has a Hirth toothing 62 into which a counter-Hirth toothing 64 arranged on the counter surface 63 of the tool head 2 is in the insertion or clamping position (FIG. 3.4 ) intervenes.
- the Hirth toothing 62, 64 takes over the fine centering of the tool head 2 relative to the drive spindle 1, so that there is no need for fine centering by means of the ring shoulder 45 and ring projection 47.
- a chamfer 67 is arranged on the upper edge of the recess 6 on the tool side.
- three individual clamping elements 34 are provided. However, these can also be combined into a one-piece, one-sided open, radially expandable and in the annular groove 33 surrounding the clamping groove 33 surrounding clamping ring, which is not shown in the figures, but in its immediate effect the clamping ring of the embodiment of Fig. 1 and 3 of EP-A-0 244 770.
- clamping cone surfaces 65 Adjacent to the lower end of the clamping cone surfaces 65 are locking recesses 66 for receiving the clamping balls 23 in the rest position.
- the starting position for clamping the tool head 2 on the drive spindle 1 is shown in FIG. 2.
- the tool head 2 is inserted with its shaft 7 into the recess 6 of the drive spindle 1 until the counter surface 63 on the end face of the tool head 2 strikes the end face 4 of the drive spindle 1.
- This is the initial clamping position.
- the clamping rod 16 is tightened in the clamping direction 17.
- the tension balls 23 emerge from the locking troughs 66 of the tension rod 16. They are acted upon by the circumference of the clamping cone surfaces 65 and spread apart in the direction 39 of expansion.
- the initial spread position is shown in FIG. 3.
- the tensioning rod 16 is displaced in the axial direction 15 counter to its tensioning direction 17 until the tensioning balls 23 again lie in the locking recesses 66 at the upper end of the tensioning rod 16, thereby marking the rest position of the tensioning device.
- the tool head 2 is pulled against a robot arm acting in the grip groove 3 against the clamping direction 17.
- the groove side wall 30 of the inner ring groove 29 presses the clamping surfaces 38
